MANIFOLDING nonm'n.

Application filed February is, 1924. Serial No. 693,485.

To all whom it may concern:

Be it known that I, ALBERT W. METZNER,- a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Manifolding Machines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to manifolding machines and more particularly to machines of said type in which a secret record'is retained within the machine, by rolling up one or more of the manifold paper webs.

The problem of obtaining a record strip involves among other things, the provision of means whereby a tight,'smoothly wound roll is formed. In manifolding machines using a pin wheel feed, or any aligning feed, and paper having holes engaged by the aligning feed means, there is the problem of obtaining a perfectly. wound record, roll without danger of placing such strain on the record web that it tears out at the holes, where the pin or other engagement is maintained. Furthermore in the pin wheel type of feed the exerting of strain on the record web will interfere with its freedom to shift about on the feed pins, and'thus will prevent the full, alignment function of the pins from coming into operation. The problems noted are chiefly present Where a full-length and full-copy record strip is produced, and in which it is necessary to feed the record web along with the webs that are issued in the form of slips to the customer.

It is the object of my invention herein to provide a mechanism for rewinding a firm and smooth record web, which web provides a full copy of all slips issued from the machine, and toprevent friction or strain of the rewind device from reacting on the pin wheel feed device used for feeding all webs in common. More specifically it is my object to introduce an additional feeding device for therecord web, adapted to engage it after it has been. passed along by the pin 'wheel feed devices, and thus to takeany and all strains on the record web which may be applied by the rotation of the. rewind roll.

I do not claim in this invention the essential novelty of maintaining a loose accumulation of paper between the pin wheel specifically pointed out feed and the rewind roll, as this is covered in United States Patent "No. 1,500,728, granted July 8, 1924. Mypresent object is to automatically maintain a partial accumulation of paper between the rewind and the pin wheels, while at the same time providing a tight web for the rewind roll to work upon. It is my specific object to time the point of operation of the rewind rollrotating devices, and of the additional feed inter mediate the roll and the pin wheels, so that the pin wheels will feed forwardenough of the record web to provide an accumulation at the beginning or the endof each feeding 1 operation, with the rewind roll andaddi tional feed devices taking hold of the web simultaneously or substantially so, after permitting this free feeding. by the pin wheels, but not before.

I also provide for-various co-related mech-- anism to assure the perfect operation of the rewind devices, and complementary feed, ing devices, and generally improve on re; wind structures in manifolding machines.

These objects and advantages Iaccom plish by'that certain construction and arrangement'of parts to be hereinafter more and claimed.

Referringibriefly to machine parts which are common to manifolding machines .of the pin wheel autographic register'-type,gI show a frame 1, in which are mounted the- .liftedaway from the pins and fed to a supply rolls 2 of manifolding paper. I indicate at 3' the writing table and at 4 the carbon paper clamping blade. At 5 I show the feed shaft of the machine which may be operated by motor or by hand by means of a handle 6. i have also indicated a stop pin 7 for the handle, which pin is displaced in order to move the handle around, by means of a pivoted trip plate-'8.

Mounted on the feed shaft are the pin Wheels 9, the normal equipment being two Wheels having the pins 10 which engage in marginal apertures in the webs of paper. A suitable stripper plate 11 is indicated, whereby the webs of paper to be issued are delivery opening, while the record web being a continuous strip, as indicated at 12, is fed down under the endof the stripper i to the rewind place. 7

On the feed shaft adjacent one side of the supporting frame is a gear 13, which drives a pair of idler gears 14. A. gear 15 mounted on a stud 16, meshes with the idler gear nearest it, Mounted so as to rock on the stud 16, is a frame 17, which carries a gear 18 that; meshes with the gear 15and because of theframe, can rotate about the gear 15 in a planetary manner. The gear 18 carries a friction wheel 19, by means of which the rewind roll is rotated.

In order to force the friction wheel 19 into driving contact with the rewind, the frame 17 is extended in an arm 20, which curves upwardly and to the rear of the gear 13, where it is equipped with a spring 21. The spring 21 engages a lever .22, which is pivoted at 23 on the supporting frame, and lies in the space between the pin wheel and the gearlii;

stud or roller 24 on the innerface of the gear 13 is arranged to strike down the end of the lever 22, after the feeding operation has been started for issuing each sales slip, or the like, and thereby increase the spring tension on the frame, and cause the friction wheel on the end of the frame tobe forced into driving position very firmly. The lever contacts with the shaft be tween the pin wheel and gear 1.3 the rest of the time and maintains the spring tension.

The rewind shaft has no special construction not common to my other machines, and is formed'ef a roller 30, a spindle 31 which is removable and a clutch ring 32 at the drive end, There is a stud 33 set in the side, wall of the frame, having a tapped hole- 34 therein to receive the end ofthe removable spindle, and a ball race 35 forftiny ball bearings. On the stud and supported on. the bearings. is a friction. wheel 36 wh h a aid 7 the hateng g and drives. the clutch ring, by means of ens.

eas ment i h a slot h rein.

In addition to the friction wheel, which lies in a plane to be engaged by the friction wheel secured to the planetary gear already noted, I mount a toothed wheel or pinion 3,8 which is used as a stopmember.

The machine is equipped with idlers 40 and 41 mounted on the same side wall as the parts above noted, and driven by means of the gear 15. These idlers drive a gear 42 011 the end of a roughened shaft or feeding roll 43, that extends across the machine in front of the pin wheels. A tension roll 44, that cooperates with the feed roll 43, is mounted on a rock shaft 45, also journaled in the side walls of the machine, by means of arms 46, 46. A coiled spring 45 on the shaft 45, engages a cross rod 47 of the machine frame which spring tends to rock; the shaft 45 to a position of forcing the tension roll down against the feed roll.

The record web is fed between these two rolls, which make up the complementary feed to which reference has been made above. Therecord web 12 passes from the pin wheels through the roll feed device now described, and thence direct to the rewind roll; The speed of feeding of the roll 43 is timed to be slightly less than that of the pin wheels.

I provide means in addition to the above mechanism for keeping the. roll feed device out of operation, and blocking the operation as well as withdrawing the friction wheels from mesh in the rewind itself.

For this purpose I mount a sliding frame 51 on a stud 52 in the machine side wall, the screw engaging a slot in the frame. he frame has a vertical end 53, which is engaged by the roller or stud 24, which has been mentioned as increasing the spring tension on the planetary frame 17. .The

frame 51 is also linked operatively at 51" to the frame 17 so that when the roller 24 en gages the frame 51 and pushes it away from the feed shaft, the outer end of the frame will engage an arm 54 on the rock shaft 45 of the complementary feed, and rock the complementary feed so as to elevate the tension roll from the feed roll, and at the same time the frame 17 will be pulled by means of the link into a position of withdrawing the friction wheel of the planetary mechanism from establishment of contact wlth the rew nd.

I find it desirable to supply an overthrow when the planetary frame is rocked to relieve the frictional driving contact.

As so constructed the machine operates as follows :the several webs of paper including the record web, which are printed and apertured alike, are placed over the pin wheels. Since I employ a pressure roll over the pin wheels, for holding the paper while same is being torn off, and also for holding the paper down on the pins without tension, I mount this roll 60, on a'pair of arms 61, on a rock shaft 62, which is spring impelled by the spring 63 toward engagement of the tension roll with the feed pins. Slots in the roll clear the feed pins, and cams 64 on the side of the pin wheels hold the pressure roll out of contact during the feeding operation. In collating the paper webs this tension device is held up by means of a latch 65 engaging the end of one of the arms 61.

When the webs have been arranged on the pins, the record web is placed over the additional feed roller 43, and brought down, and mounted on the rewind roll. then begin, the operator releasing the feed handle, for each operation which will be a complete rotation of the handle.

The start of the operation of the feed pins which jog the paper webs into line and feed them forward will be to accumulate some of the record webbetween the complementary feed and the pin wheels, since thestud or roller 24 is so placed as to hold the tension member of the complementary feed out of contact for a. small portion of the feed, and also to hold out the rewind feed. As the feeding motion progresses the complementary feed starts up by the tension roller being released to come down into contact, and the rewind begins also. 'The beginnmg of the rewind will be without frictional slip because by the time vtheroller 24 has moved away from engagement withthe frame 51 that controls the complementary feed, it will pick up the lever 22 and increase the spring tension on the rewind planetary frame. During the feed, the paper will accumulate between the pin wheel and the friction or complementary feed.

Toward the end of the feeding operation the roller 24 will again pickup the frame 51, and will thus open up the complementary feed, and also release the friction drive of the rewind. I

At the time of release of the rewind, the

stop will fall into engagement with the rewind friction wheel and positively stop the rewind, and the accumulated paper will fall down over the friction feed, tobe snapped up as the rewind feed begins its next operation.

It should be observed that the exact timing of the feeding devices above noted, need not be as stated, since the releasing of the times. The feed can two additional feed elements could take place at any point of the feed, within certain limits, and I do not wish to confine my as Well be adapted, and timed to operate together with the complementary feed.

It is desirable that the complementary feed'should be by means of rollers held together by spring tension, since this provides a firm grasp across the record web, and permits the rewind to form up a tight, smooth roll, which is highly desirable in manifolding' machines.

Since no paper accumulates on the complem-entary feed devices, the timing of the operation thereof can be maintained the same as that of the pin wheels by means of the gearing, sothat an accumulation of paper will be maintained between the pin wheels and the Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: v
